After 4.6 all bile troll axe attacks go through block 100%.
Pre 4.6 blocking will reduce axe attack damage significantly.
ya this has happened to me too. is this a bug
was just about to make a topic on this. i was playing WHC and bile trolls would always break my shields and send my flying with the swipe attacks, but never do alot of dmg. Now they do max dmg through 3 shields on rapier with the swipe attack.
